NAME: @code{diag} - get diagonal part of a matrix

DESCRIPTION:
This function get the diagonal part of a matrix.
@example
csr<Float> a;
dia<Float> d = diag(a);
@end example
TODO:
Build a csr matrix from a diagonal one or from a vector:
@example
dia<Float> d;
csr<Float> a = diag(d);
vec<Float> u;
csr<Float> b = diag(u);
@end example
